BELT-PUNCH.

SPECIFICATION forming part Of Letters Patent No. 732,030, dated June 30,1903.- Application filed September 10,1902. Serial No. 122,864. (Nomodel.)

To all whmn it may concern:

Be it known that I, DAVID T. ALLEN, a citizen of the United States,residing at Maplelake, in the county of Wright and State of Minnesota,have invented certain new and useful Improvements in Belt-Punches; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to improvements in belt-punches; and the mainobjects of the invention are, first, to provide a belt-punch of thelever-operated class with a gap deep enough to receive the end of anyordinary working belt so far into it that the holes for the lace may bepunched the required distance from the end of the belt and still havethe fulcrum of the levers so near the punch proper that the punch may beoperated with great ease even on heavy belting second, to provide abelt-punch with means indicating how far from the end of the belt theholes are being punched; third, to make such punch as light and neat andcompact as possible; fourth, to make such punch in a cheap manner ofconstruction. These and other objects I attain by the novel constructionand arrangement of parts illustrated in the accompanying drawings, inwhich-- Figure 1 is a side view of my complete beltpunch. Fig. 2 is atop View of the main lever A in Fig. 1. Fig. 3 is a bottom view of thesecondary lever B in Fig. 1. Fig. 4 is a top view, and Fig. 5 a sideview, of the arm 0 in Fig. 1.

Referring to the drawings by letters of reference, it will be seen thatthe punch is to some extent constructed on the principle of a pair oftongs, having its two levers A and B fulcrumed on the pivot D,which passthrough the crossing-point, so that the long arms of the lovers formhandles adapted to be grasped and forced together with one hand, whilethe short front ends of the levers are provided one with a belt-punch orpunching-tube E and the other one, F, supports the front end G of aVertically-swinging arm 0, which is a cushion P, of soft metal,preferably copper,

to prevent the punch E from getting dull when penetrating the belt; Saidcushion I prefer to secure on the arm by giving it a.

stem Q, which fits tightly in the aperture R of the arm, so that whenthecushionisworn out it may be removed by inserting a nail or likeobject upwardly through the aperture and then put in a new cushion.

Adjacent the gap or mouth G of the punch I provide upon one side of themain or primary jaw a scale indicating various distances from the centerof the punch proper. In the presentinstance the scale has only fourmarks, with 1- 1, 13;, and 111; at the ends of the marks to indicate ininches the distances the lacing-holes are punched from the end of thebelt; but it is evident that this scale may be varied bothas toarrangement and length.

In my preferred construction of this device I make the lever A with aslot S extending as far as possible throughout it. In this slot I placethe thinner lever B, whichis,however, enlarged at its upper edge by theside ribs T to make it more adapted to the pressing of the hand on it.This construction lends stiffness to the lovers with a minimum of metalin them.

While the lever A may be cast with the slot S cored out, I prefer toproduce the slot S and the spring-pocket J by casting the lever A inhalves separable at the line art in Fig. 2 and secured together by therivets U V W, passed through the two halvesand the intermediate supportsX Y Z, formed upon one of them. I

In the operation of the devicethe belt is placed, like N, with the endto the desired mark of the scale, and as the levers A B are squeezedtogether the punchings of the belt pass upward and out at E The centerof the pivot H should properly be placed slightly below a horizontalline across the face of the punch, so that whatever little curve thecushion may make is minimized by being divided above and below ahorizontal line.

It will be understood that the main advanof the gap G which it isnecessary to have quite deep in order to reach with the punch E to thedesired parts of the large belts.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-- 1. A belt-punch comprising a primary' and asecondary lever pivoted together at their crossing, a punching-tubesecured in the front end of one of the levers, a cushioned memberadapted to move to and from the face of the punch, the front end of thesecondary lever being arranged so as to force the cushioned membertoward the face of the punch, and a spring tending to depress thecushioned member away from the punch, said primary lever having the gapor notch Gr forming a mouth for the end or edge of the belt operatedon,said mouth extending rearwardly aboveand beyond the pivot at thecrossing of the levers.

2. In a belt-punch, the combination with a primary and a secondary levercrossing each other and being pivoted at their crossing, a punching-tubesecured in the front end' of the primary jaw, said primary jaw having abelt mouth or gap extending rearwardly above and beyond the pivotedjoint, the downwardly spring-pressed swinging arm 0, pivoted rearward ofthe gap and resting normally upon two points of the secondary jaw, oneforward and one rearward of the pivot at the crossing, of a softmetallic cushion on said swinging arm opposite the punching-tube.

3. As an improved article of manufacture, the combination in abelt-punch of a primary lever slotted almost throughout its entirelength, a secondary thin lever pivoted in said slot and having the sideribs '1 upon its longer arm, the cushioncarrying spring-pressed arm 0pivoted in said slot and supported by the front end of the secondarylever, and a punching-tube secured in the front end of the primarylever.

4. As an improved article of manufacture, the combination in abelt-punch of a primary lever slotted almost throughout its entirelength, a. secondary thin lever pivoted in said slot and having the sideribs T upon its longer arm, the cushion-carrying spring-pressed arm 0pivoted in said slot and supported by the front end of the secondarylever, and a punching-tube secured in the front end of the primarylever; said slot in the primary lever'be ing formed by making the leverin two halves and securing it together withinterveningsupports.

In testimony whereof I aftix my signature in presence of two witnesses.

DAVID T. ALLEN.
